Windows UI Library 2 Release Notes
The Windows UI Library (WinUI) is hosted on GitHub.
We encourage you to file bug reports, feature requests and community code contributions in the Windows UI Library repo.
WinUI includes two NuGet packages:
Microsoft.UI.Xaml: Controls and Fluent Design for UWP apps. This is the main WinUI package.
Microsoft.UI.Xaml.Core.Direct: Low-level APIs for use in middleware components.
You can download and use WinUI packages in your app using the NuGet package manager: see Getting Started with the Windows UI Library for more information.
For more info, design guidance, and code examples, see Design and code Windows apps.
The WinUI 2 Gallery app includes interactive examples of most WinUI 2 controls, features, and functionality.
If the gallery app is installed already, click WinUI 2 Gallery to open it.
If not installed, download the WinUI 2 Gallery from the Microsoft Store.
You can also get the source code from GitHub (select the winui2 branch).
How-to articles for Windows UI Library controls are included with the Universal Windows Platform controls documentation.
API reference docs are located here: Windows UI Library APIs.
